One thing to remember when watching this video not to bring elbow forward (which he does at 1:52). This is for very beginners, I think (the reason some people do that) a lot of coaches tells that to the student in the very beginning to make sure they hit the bird at a high point. So, I won't focus so much on bringing the elbow forward. What he did at 1:37 or 1:41 is more correct form. I am sure he doesn't bring the elbow forward like 1:52 when he smashes.
Lee Jae Bok Style:
I got some private lessons from Lee Jae Bok and I know his technique people thing is a lot different and you guys call it a pan-handling grip, it's actually not. So, he turns the racket 10 deg or less which is no way panhandle grip. So, please don't call that. He uses pronation. You have to, there is no other way. But he focuses on wrist more. If you get more court time with him, you will understand wrist can be crazy deception. We have this mindset that powerful smash = best player. I know it's a cool thing. I still want to make my smash powerful even though i can improve on other things. But he wants people to learn the wrist power, you can do any shot once you master this technique. Being the front player I find I can cut off more easily also once in a while I can do a punch deceptive clear and I get people off balance.
I asked him the same question, why use so much wrist, what about pronation. I don't remember exactly what he said but it was something along the line that it was overrated. He said to use 10% pronation and focus 90% on my wrist power. You start with that as you basic. And then you will get a feel for the bird, you can feel you clean you are hitting. Then you start to add bit more pronation and experiment, until you find the sweet spot for you body (a perfect ratio of using wrist and pronation). That's what I have experienced. I wish my wrist was like him, his wrist is super strong, I feel he can smash faster just using his wrist than some provincial players. So, please don't get hung up on his grip and more use of wrist. I used to think that way too.
Few things are very similar and LJB focuses on some points which people usually don't tell you about.
Here are some random thoughts from me... which helped me fixed my overhead shots.
1. Before the smash stop (don't be wobbly, need to be very relaxed and balanced)
Loading Position
Time 2:55 [video=youtube;Bl9L5Z-6ufc]https://www.youtube.com/watch?v=Bl9L5Z-6ufc[/video]
1a. Then stay both feet on the ground, go into loading position and execute the smash.
1b. Jump up a bit (more 80 to 90% power from the racket leg), loading position and smash.
Try not to spend too much time at the loading position. it should be very quick. From the relaxed position (even when I jump i am still relaxed), load and smash. The part load and smash is a very quick motion. The shorter and compact it is, the more power you will get. Also, don't slice the bird, if you don't hear a clean sound try changing the grip. Use the LJB 10 deg change, that helped me.
Not sure how to explain the body rotation, that took me really long time to learn. I mean to make it one thing, the smash and whole body moving at the same time, so I can get power from legs, core etc. If I look at this video 2:56, you can try that except move the right leg forward. take a step. This is for beginner with not jumping.
2. LJB actually use pronation, if you watch him in slow motion you will see. But he focuses a lot on wrist, because I think a lot of people focus too much on pronation. Bio mechanically you need to use forearm pronation to get power. But the important thing to remember is to have very concentrated motion. That's why I think he told me to use 10% pronation but the pronation will come naturally.

3. As you are hitting, you need to move forward (at least not fall back)
4. Using more wrist gives you a lot of deception. you can clear using a very shot motion and you can also use wrist to do a quick smash (when playing fast doubles most of the time you have no time to load).
5. Train your wrist using a 10lb dumble, you can get a lot of power.
PS: I always think there are room for improvements. If some of you out there think I mentioned anything you don't agree, please feel free to comment.
